Activate B to A upgrade feature, following gtl activation procedure with "license active" command.
If LPUs are more than provided licenses, use "service-enhance slot (slot number)" command to choose which LPU to be upgraded to A type.
Use "display gtl binding-info slot all" command to check LPU enhanced functionality.
The board still will be recognized as B type, which is the physical PCB board version, because A type is only logical upgrade.
